The combo regulator is a combination regulator and shut-off valve. The pressure is set using the screwdriver adjustment in the center of the on/off knob. Turning the knob counterclockwise provides positive shutoff, while clockwise rotation restores gas pressure to within 0.5 psi of the setpoint.
The regulator is machined from aluminum bar stock and then hard-anodized to provide contamination-free service. It features a stainless steel diaphragm and Viton-sealed stainless poppet. The compact size (3" x 1.125" diameter) saves panel space and permits installation anywhere that an 11/16" hole can be located (mounting hardware is supplied)
Can be ordered with 1/16" or 1/8" Valco internal fittings or 1/8" external fittings. Other configurations are available in OEM quantities.
The influence of supply pressure on outlet pressure is less than 0.1 psi per 10 psi change in supply pressure.
